P0430 Catalyst System Low Efficiency Bank 2
Your O2 sensor, wiring or Cat on the Passenger side is acting up… Do you even have Cats on there?

B0605 BCM Internal Memory Malfunction
Is this an H or a C.? Have you replaced any other parts on the car inside or out?

Well anything is possible as far as glitch's go... Did you get a tune after the Header install? Alot of times the COT needs desinsitized or tuned out to eliminate the Cat Overtemp (COT) which is common with Highflow Cats...

I was more concerned about your BCM to be honest... Keep an eye on it and post back in here if they crop back up again... We'll get Mr. Bill Curlee on the job!
